Geotextiles

Separation, filtration and protection in one layer

Naue geotextiles are mechanically bonded nonwovens for separation, filtration and protection of liners, used as parts of drainage and reinforcement layers. The portfolio comprises Secutex®, Secutex® Green, Secutex® H for hydraulic engineering and Naue GlacierProtect for glacier and snowfarming applications.

Geotextiles: frequently asked questions

Geotextiles deliver separation, filtration, protection, and are used in drainage and (in combination with a geogrid) reinforcement applications. Naue Secutex® mechanically bonded nonwovens are optimised for separation, filtration and protection. For protection above geomembranes, specify a heavy Secutex® protection nonwoven.

Secutex® H is the hydraulic geotextile (BAW-approved) for revetments, bank and scour protection in hydraulic engineering.

Naue GlacierProtect made of Secutex® Green G1 is a high-reflectivity geotextile system specifically engineered to slow ice and snow melt on glaciers and ski areas (snowfarming).

Yes. All relevant Secutex® variants carry CE marking under CPR 305/2011 as well as other specific certificates.

Secutex® opening sizes (O90) are engineered to match the soil grading. Naue’s Engineering & Design Department (EDD) provides project-specific filter assessments per the Cistin/Ziems and Heerten criteria.

Yes. Naue Secutex® can be installed at low temperatures down to -20 °C. The substrate must remain stable and free of snow / ice contamination.

Yes. Secutex® can be sewn for high-tension overlaps.
